The Sun Hydraulics DNDAXEV712 (DNDAXEV712) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered to operate without the need for minimum hydraulic pressure and features a fatigue-rated solenoid tube assembly capable of withstanding pressures up to 5000 psi (350 bar). It offers multiple manual override options, although some overrides are not compatible with weatherized coils. The D and L control models include a detent mechanism designed for temporary actuation, with an estimated mechanical life of about 7,000 cycles. The valve's EPDM seals make it suitable for systems using phosphate ester fluids while avoiding petroleum-based products to prevent seal damage. Utilizing a wet armature design, the valve's coil-generated heat is absorbed by the surrounding fluid\u2014important when using water-glycol mixtures that may degrade into varnishes over time. The solenoid's magnetic design ensures high efficiency and reliable shifting with interchangeable coils compatible across Sun Series 1 products. Coil connectors can achieve ratings up to IP69K for enhanced environmental protection. The valve incorporates Sun's floating style construction to reduce binding risks from installation or machining inconsistencies. It fits into cavity T31A and belongs to Series 1, supporting a capacity of 10 gpm (40 L/min) at maximum operating pressures of 5000 psi (350 bar). Typical response time is approximately 50 ms, with leakage rates capped at 10 in\u00b3/min (3000 psi). The switching frequency reaches up to 15,000 cycles per hour. Installation requires torque between 30-35 lbf ft (41-47 Nm), and its compact design weighs around .60 lb (.30 kg).

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is not compatible with weatherized coils.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
